ROOF SHINGLE.

Application filed February 5, 1927. Serial No. 166,102.

of the shingles at the expense of a minimum amount of time and labor. The above and other ob ects will become a: apparent in the description below, in which like characters of reference refer to like named parts in the drawings.

Referring briefly to the drawings, Fig. 1 is a view of a roof in the process of being covered with the shingles of this invention.

F ig. 2 is a sectional view taken on the line 2-2 of Fig. 1, showing the interlocking means.

Fig. 3 is av perspective view of a single shingle.

Fig. i is an enlarged perspective view of one of the interlocking tongues, showing the means by which it is secured to the shingle.

Referring in detail to the drawing, the numeral 10 indicates a shingle of the commonest shape. Tongues 11 protrude from the underside of two diagonally opposite corners, these tongues being attached to the shingle by inserting the prongs 12 of the tongues into the shingle. the shingle between the above-mentioned tongues, a slot 13 is cut through the shingle, the material of the shingle surrounding the slot being strengthened by a reinforcing member 14.

These shingles are applied to the roof as follows. The shingles 16 and 17 are layed In one corner of on the roof side by side, and the tongues 11 are bent upward. The shingle 15 is then layed above them so that the tongues pass through the slot 13 of the shingle 15. The latter is then pressed against the roof, and the tongues 11 are turned outward and downward against the shingle 15. These three shingles are then looked to each other at this point. This procedure is continued with the other shingles, until the roof has been covered.

To further illustrate the manner of attaching the shingles, it is to be noted that, after the shingles 18 and 19 have been interlocked with those below them, the tongues 11 of these shingles lie as shown in Figure 1. Before the shingle above them is placed on the roof, the adjacent edges of these shin gles are bent upward to free their tongues, and the latter are then both bent upward to be ready toaccommodate the slot 13 of the shingle which is then to be placed in position.

What is claimed is as follows:

In an overlapping fabricated shingle, means for locking the shingle with adjacent shingles on the roof comprising tongues,

ears on said tongues piercing said shingles,

an elongated opening at one corner of each shingle, said elongated opening being adapted to be superimposedover said tongue of another shingle, said ears on said'tongues being bent at right angles to a part of the tongue to secure said tonguev to a corner of the shin le, and a sleeve having an elon gated opening seated to said'shingles around said elon ated opening to form a reinforcement and receive upwardly bent portions of said tongues of shingles beneath a shingle having said sleeves.
